  • the open ends 31, 32 of the tubular body 35 allow a pressure equalization between the upper gas volume and the pressure on the already existing liquid column, so that turbulence in the liquid Gas 1 can be minimized or completely suppressed.
  • FIG. 6 shows the helium consumption V (Heii qu ) for several series of experiments 1, 2, 3, ... (abscissa) without (curve A) and with (curve B) of the receiving line according to the invention. Only in the first cooling of the cryostat a high liquid consumption was measured in both cases.
